SLE1-D Series Magnetic Starter

Main Technical Parameters:

Principle of operation

The working principle of the SLE1-D Series Magnetic Starter is based on the interaction of electromagnetic induction and electromagnetic force. When the control power supply is energized, the electromagnetic coil generates a magnetic field, which attracts the iron core to move and closes the contacts, and the motor is supplied with power and starts to run. When the control power supply is de-energized, the magnetic field disappears, the iron core resets under the action of the spring, the contacts are broken and the motor stops running.

Types and Features

There are various types of SLE1-D Magnetic starters, such as direct on-line (DOL) SLE1-D Magnetic starters, star-delta (Star-Delta) starters, autotransformer starters and so on. Different types of SLE1-D Magnetic starters have different characteristics and scope of application.

1.Direct on-line (DOL) SLE1-D Magnetic starter:

Simple structure, low cost.

Suitable for starting and stopping control of small power motors.

2.Star-Delta (Star-Delta) starter:

By changing the wiring of the motor, it realizes the purpose of reducing voltage and current during starting.

Suitable for medium power motor starting control.

3.Autotransformer Starter:

Utilizes an autotransformer to reduce the voltage and current when starting a motor.

Applicable to the starting control of high power motors.

Application Scenarios

SLE1-D Magnetic starters are widely used in various industrial and commercial applications such as manufacturing, construction, agriculture, and transportation. They are used to control various types of motors such as three-phase asynchronous motors, DC motors, etc. for automated production and remote control of equipment.
